Term1/9

What kind of trait is present when many different genes control a single trait such as skin color

Definition1/9

polygenic

Term1/9

What common condition is caused by the presence of three copies of chromosome 21

Definition1/9

down syndrome

Term1/9

What is expressed when both alleles for a gene are equally expressed as in human blood type

Definition1/9

This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=i

IAIb = AB blood type

IbIb = B blood type

Iai = A

IaIa = A bloody type

Ibi = B blood type

ii = O blood type

Term1/9

What kind of cross predicts the inheritance of two characteristics

Definition1/9

dihybrid cross

Term1/9

What is the most common fatal genetic disease in the United states

Definition1/9

cystic fibrosis (:

cystic fibrosis :)

cystic fibrosis ^-^

Term1/9

Which term means the state of having two different alleles for the same trait

Definition1/9

Two different alleles for the same trait are heterozygous.

No, Its homozygous. This answer is incorrect as homo = same.

Term1/9

What causes disorders such as klinefelter syndrome and turner syndrome

Definition1/9

non disjunction of sex chromosomes

Term1/9

A child is born with type ab blood. which of these statements is true

Definition1/9

A+ Neither parent can have type O blood

Term1/9

What is a example of a environmental effect on phenotype

Definition1/9

Mental retardation
